A Posteriori Error Estimates for a Nonconforming Finite Element Discretization of the Stokes–Biot System

open access: yesDiscrete Dynamics in Nature and Society, 2022
This paper presents an a posteriori error estimator for a (piecewise linear) nonconforming finite element approximation of the problem defining the interaction between a free fluid and poroelastic structure.

Inversion for Geofluid Discrimination Based on Poroelasticity and AVO Inversion

open access: yesGeofluids, 2019
Geofluid discrimination plays an important role in reservoir characterization and prospect identification. Compared with other fluid indicators, the effective pore-fluid bulk modulus is more sensitive to the property of fluid contained in reservoirs.

On the Holographic Bound in Newtonian Cosmology

open access: yesEntropy, 2018
The holographic principle sets an upper bound on the total (Boltzmann) entropy content of the Universe at around 10 123 k B ( k B being Boltzmann’s constant).

Thermodynamic Properties of the Parabolic-Well Fluid

open access: yesFrontiers in Physics, 2021
The thermodynamic properties of the parabolic-well fluid are considered. The intermolecular interaction potential of this model, which belongs to the class of the so-called van Hove potentials, shares with the square-well and the triangular well ...

Fluid flow approximation of PEPA models [PDF]

open access: yesSecond International Conference on the Quantitative Evaluation of Systems (QEST'05), 2005
In this paper we present a novel performance analysis technique for large scale systems modelled in the stochastic process algebra PEPA. In contrast to the well-known approach of analysing via continuous time Markov chains, our underlying mathematical representation is a set of coupled ordinary differential equations (ODEs).

Wave focusing by submerged islands and gravitational analogues

open access: yesPhysical Review Research, 2022
We study water waves propagating over a smooth obstacle in a fluid of varying depth, motivated by the observation that submerged islands in the ocean act as effective lenses that increase the amplitude and destructive power of tsunami waves near focal ...

Bottom Multi-Parameter Bayesian Inversion Based on an Acoustic Backscattering Model

open access: yesJournal of Marine Science and Engineering
The geoacoustic and physical properties of the bottom, as well as spatial distribution, are crucial factors in analyzing the underwater acoustic field structure and establishing a geoacoustic model.

Blade coating analysis of a Williamson fluid

open access: yesResults in Physics, 2017
In this article, a mathematical model of a blade coating analysis of the thin film of a Williamson fluid is developed when it passes through the small gap between a blade and a moving substrate.

Entropy approximations for simple fluids

open access: yesPhysical Review E
Liquid state entropy formulas based on configurational probability distributions are examined for Lennard-Jones fluids across a range temperatures and densities. These formulas are based on expansions of the entropy in series of $n$-body distribution functions. We focus on two special cases.
